DETAILED DESCRIPTION

The following discussion provides examples of systems and techniques for obtaining and maintaining maintenance records for various assets. As will be described in more detail below, a computing device in one embodiment may be wirelessly coupled to a measurement device when the computing device is placed in proximity with the computing device. Upon measuring one or more parameters of a device under test (DUT), the measurement device may provide the measured parameter(s) to the computing device in the form of measurement data. In some embodiments, the computing device associates the measured parameters with the corresponding DUT from which the measurements were obtained and provides the associated measured parameter to, for example, a service provider for subsequent access. In another embodiment, the measurement device itself is configured to associate the measurement parameters with the DUT and provide the associated measurement parameters to the service provider.

Prior to discussing the details of various aspects of the present disclosure, it should be understood that one or more sections of the following description may be presented in terms of logic and operations that may be performed by conventional electronic components. These electronic components, which may be grouped in a single location or distributed over a wide area, generally include controllers, microcontrollers, control units, processors, microprocessors, etc. It will be appreciated by one skilled in the art that any logic described herein may be implemented in a variety of configurations, including but not limited to hardware, software, and combinations thereof. The hardware may include, but is not limited to, analog circuitry, digital circuitry, processing units, application specific integrated circuits (ASICs), and the like, and combinations thereof. In circumstances where the components are distributed, the components are accessible to each other via communication links.

While some embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the disclosure. Each embodiment described in this disclosure is provided merely as an example or illustration and should not be construed as preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Additionally, it will be appreciated that embodiments of the present disclosure may employ any combination of the features described herein.

FIG. 1 is a block diagram of a system 100 for obtaining and maintaining maintenance records in accordance with aspects of the present disclosure. The system 100 includes at least one asset 104 to be tested (also referred to herein as a device under test 104 or DUT 104) and one or more measurement devices 108 configured to measure one or more parameters of the DUT 104. For example, each of measurement devices 108 may include one or more sensors, probes, etc., for measuring one or more parameters of a DUT 104. It will be appreciated that the measurement device 108 may be installed in situ at the DUT 104 or may be brought to the DUT 104 by a user, such as a technician. The DUT 104 may include any equipment, device, circuit, structure, component, and the like having at least one parameter that can be tested by a measurement device. In some embodiments, the DUT 104 may include, but is not limited to, a pump, a motor, a transistor, a cable, a switch, a breaker, a generator, a transformer, a power storage source, etc. In a non-limiting example used throughout the disclosure, the DUT 104 includes an electric motor. The measurement device 108 may be a measurement and/or calibration device, including but not limited to a multimeter, oscilloscope, thermal imaging system, thermometer, calibration tool, cable tester, etc. In that regard, the one or more parameters to be measured by the DUT 104 may include electrical parameters, temperature, pressure, visible or invisible light waves (including images), and the like. In non-limiting examples used throughout the disclosure, the measurement devices 108 are a digital multimeter and a thermal imaging system.

The system 100 also includes at least one computing device 112 configured to be coupled in communication with the measurement device(s) 108. Each computing device 112 can be coupled in communication with the measurement device(s) 108 via any known or future developed wireless or wired communication protocols. In some embodiments, the computing device 112 and the measurement device(s) 108 can be configured to be coupled via Near Field protocols, Infrared protocols, Bluetooth protocols, IEEE 802 protocols, etc. As will explained in more detail below, the computing device 112 in one embodiment may be wirelessly coupled in communication with the measurement device 108 by placing the computing device 112 in proximity with the measurement device 108. In that regard, the computing device 112 is configured to receive data, such as measurement data, from the measurement device 108 via the wireless (or wired) communication link. In some embodiments, the computing device 112 may be, for example, a mobile computing device, such as a tablet or a smartphone, a personal computing device, a laptop computing device, a personal digital assistant, and the like.

The computing device 112 is also coupled in communication to a maintenance service provider 124 via a network 116 using any suitable wired and/or wireless communication protocol, including Internet, cellular and satellite protocols. The network 116 can be a Local Area Network (LAN), a large network, such as a Wide Area Network (WAN), or a collection of networks, such as the Internet. In that regard, the computing device 112 may be configured to provide measured data received from the measurement device 108 to the maintenance service provider 124 via the network 116. Similarly, the computing device 112 may be configured to receive data from the maintenance service provider 124 via the network 116. In one embodiment, the computing device 112 is configured to communicate with the measurement device 108 via the network 116 or other communication systems described herein. Although in the illustrated embodiment, the maintenance service provider 124 may be coupled to the computing device 112 via the same network 116 by which the measurement device 108 is coupled to the computing device 112, it is to be appreciated that the network coupling the computing device 112 to the maintenance service provider 124 may be distinct from the network coupling the computing device 112 to the measurement device 108.

Generally described, the maintenance service provider 124 may include one or more interconnected computing devices (not shown), such as personal computers, server computers, embedded computing devices, mobile computing devices, and the like. It is to be appreciated that each of the computing devices may include a variety of hardware components and program modules for operation, which will not be described herein in detail in the interest of brevity. The maintenance service provider 124 may further include or be coupled to one or more data stores 128 for storing data, such as the measurement data received from the computing device 112.

In the illustrated embodiment, the maintenance service provider 124 and the computing device 112 are further coupled to technical support 132 via the network 116. The maintenance service provider 124 may be configured to initiate contact with technical support 132 and provide suitable information to allow technical support 132 to be placed in communication with the computing device 112. For instance, technical support 132 may be configured to send texts or emails to the computing device 112 via the network 116 in response to a request from the maintenance service provider 124. It is to be appreciated that technical support 132 is optional. In some embodiments, technical support 132 may also be integrated with the maintenance service provider 124.

Turning now to FIG. 2, there is shown a block diagram of a representative component architecture of one example of a computing device 112. The computing device 112 includes hardware components, such as a central processing unit (CPU) or processor 240, communication circuitry 244, I/O interface 248, and memory 250 suitably interconnected via one or more buses 252. Depending on the exact configuration and type of computing device, the memory 250 may include system memory in the form of volatile or nonvolatile memory, such as read only memory (“ROM”), random access memory (“RAM”), EEPROM, flash memory, or similar memory technology. Those of ordinary skill in the art and others will recognize that system memory typically stores data and/or program modules that are immediately accessible to and/or currently being operated on by the processor 240. In this regard, the processor 240 serves as a computational center of the computing device 112 by supporting the execution of instructions.

The memory 250 may also include storage memory. The storage memory may be any volatile or nonvolatile, removable or non-removable memory, implemented using any technology capable of storing information. Examples of storage memory include but are not limited to a hard drive, solid state drive, CD ROM, DVD, or other disk storage, magnetic cassettes, magnetic tape, magnetic disk storage, and the like. The information stored in the storage memory includes, but is not limited to, program modules and data to be accessed by the processor 240. Generally, program modules may include routines, applications, objects, components, data structures, etc., that perform particular tasks or implement particular abstract data types. It will be appreciated that system memory and storage memory described herein are merely examples of computer readable storage media.

In the embodiment shown in FIG. 2, the memory 250 stores an operating system 254 for controlling the operation of the computing device 112. In one embodiment of the disclosure, the operating system 254 provides a graphical operating environment, such as Microsoft Corporation's WINDOWS® or WINDOWS® Mobile, LINUX, Google's Android, Blackberry OS, or Apple's Leopard or mobile iOS graphical operating system, etc., in which activated applications or program modules are represented as one or more graphical application windows with an interface visible to the user, such as a graphical user interface (GUI). To interact with the computing device 112, the input/output interface 248 may include a variety of components that enable the computing device 112 to obtain inputs from and provide outputs to a user and/or other devices. The input/output interface 248 may include, but is not limited to, a display, such as an LCD, an LPD, OLED display, etc., a keypad, hard or soft keyboards, a touchpad, controls, physical buttons, scroll wheels, a digital pen, trackballs, a joystick, etc. In one embodiment, the display, such as display 270, may be configured as a touchscreen. The I/O interface 248 also receives input from, and in some embodiments may provide output to, the measurement device(s) 108.

The memory 250 also stores a measurement device and service provider interface 256 that when executed by the processor 240, provides functionality to the computing device 112. Such functionality may include, but is not limited to, interactions with one or more measurement devices 108, receiving measurement data from the measurement device 108, sending and receiving data, such as measurement data and historical data, to/from the maintenance service provider 124, associating measurement data with a particular DUT 104, obtaining a maintenance route for obtaining measurement data from a plurality of DUTs 104, etc. To that end, the interface 256 may include one or more applications or program modules, which can be written in a programming language, such as C, C++, COBOL, JAVA™, PHP, Perl, HTML, CSS, JavaScript, VBScript, ASPX, Microsoft .NET™ languages such as C#, and/or the like. It will be appreciated that the functionality of the service provider interface 256 may be split among multiple program modules or sub-modules. As will be described in more detail below, execution of the interface 256 by the processor 240 in some embodiments generates one or more user interfaces having one or more interface elements. In some embodiments, the one or more user interfaces are presented to the user via the display 270 in a hierarchal manner.

Still referring to FIG. 2, the communication circuitry 244 comprises one or more components for communicating either directly with measurement device 108 or indirectly with the measurement device 108 over network 116 using any suitable wired or wireless communication protocols. The one or more components of the communication circuitry 244 may also be employed to communicate with the maintenance service provider 124 and/or technical support 132, etc. The components may include modems, transmitter/receiver and/or transceiver circuitry, for performing communications over the one or more networks. To communicate wirelessly, the communication circuitry 244 may include one or more suitable antennas (not shown). For ease of illustration, FIG. 2 does not depict analog to digital converters, digital to analog converters, amplifiers, device controllers, etc., which will typically be included with the communication circuitry. However, since these and other components that may be included with the communication circuitry are known in the art, they will not be described in detail here.

The functionality of the interface 256 will now be described in more detail. In some embodiments, the interface 256 allows the computing device 112 to be wirelessly coupled to a measurement device 108 (FIG. 1) when the computing device 112 is placed in proximity with the measurement device 108. In that regard, the measurement device(s) 108 includes a communication interface 140, including a transmitter, a transceiver, and/or the like, configured to couple with the computing device 112 and to transmit signals thereto. When the computing device 112 is in proximity with the measurement device 108, the interface 256 causes the communication circuitry 244 to perform a coupling process or “handshake” so that the computing device 112 is capable of receiving one or more signals from the measurement device 108, thereby associating the computing device 112 with the measurement device 108. The coupling process can be automatic or user initiated via a switch, graphical user interface element, or the like. In one non-limiting embodiment, the computing device 112 and the measurement device 108 are configured to be paired via Bluetooth® and/or the like.

Once coupled, the computing device 112 may be configured, by way of interface 256, to receive measurement data from the measurement device 108. The measurement data may be provided from the measurement device 108 to the computing device 112 via wireless communication established by placing the computing device 112 in proximity with the measurement device 108, by network 116, or over another communication network. In particular, the measurement device 108 is configured to provide measurement data or other data generated by the measurement device 108 to the computing device 112. Although only one computing device and one measurement device are shown, it is to be appreciated that a plurality of computing devices may be configured to associate with a plurality of measurement devices.

The interface 256 also allows the computing device 112 to communicate with the maintenance service provider 124 via the network 116. In that regard, the maintenance service provider 124 may be configured to send data to and receive data from the computing device 112. By way of the interface 256, the computing device 112 may be further configured to access a help service and a maintenance library stored in the data store 128 of the maintenance service provider 124. The maintenance library may include maintenance data, such as a taxonomy of assets, measurement data, reference data, maintenance operator comments, high priority measurements needed, common asset problems, etc.

As understood by one of ordinary skill in the art, a “data store” as described herein may be any suitable device configured to store data for access by a computing device. One example of a data store is a highly reliable, high-speed relational database management system (DBMS) executing on one or more computing devices and accessible over a high-speed packet switched network. However, any other suitable storage technique and/or device capable of quickly and reliably providing the stored data in response to queries may be used, and the computing device may be accessible locally instead of over a network, or may be accessible over some other type of suitable network or provided as a cloud-based service. A data store may also include data stored in an organized manner on a storage medium known in the art. One of ordinary skill in the art will recognize that any separate data stores described herein may be combined into a single data store, and/or any single data store described herein may be separated into multiple data stores, without departing from the scope of the present disclosure.

The interface 256 further allows for the manipulation of data received from the measurement device 108 and the maintenance service provider 124, as well as to create records. For instance, the interface 256 may be configured to create, and in some embodiments, edit and store records for various DUTs 104A-104N. The created records may include asset name, asset type, measurement data received from a particular measurement device, time of service, comments from the maintenance staff, and other information related to maintaining the assets. The created records may be provided to the maintenance service provider 124 for storage in the data store 128. Additionally, the interface 256 may be configured to access previously stored records for various assets stored in the data store 128 of the maintenance service provider 124 and transmitted to the computing device 112. The stored records can be downloaded by the computing device 112 or streamed to the computing device 112. In such an instance, the computing device 112 may also include audio/video converters/decoders and/or other device appropriate circuitry and/or software in order to view streaming data from the maintenance service provider 124. The stored records may include analyzed data from a plurality of stored records, such as historical measurement data, trends, reference data, and the like. In some embodiments, the interface 256 may be further configured to edit previously stored records for various assets stored in the data store 128 of the maintenance service provider 124.

The interface 256 may also allow a user to associate measurement data received from the measurement device 108 with the DUT 104 from which the measurement data was obtained. To that end, the interface 256 may provide a graphical list of a plurality of assets which a user may select as the DUT. In some embodiments, each asset is associated with an asset record in the memory 250 of the computing device 112 or stored in the data store 128 of the maintenance service provider 124. The asset record may include information, such as asset type, name, location, serial number, and route. In one embodiment, the list of the plurality of assets comprises a list of assets in a particular location. Accordingly, measurement data may be associated with the DUT (i.e., the asset which the measurement data was obtained) by selecting one of the assets from the list or by selecting an asset record. In other embodiments, the measurement data may be associated with the DUT 104 from data obtained by an automated system 274, such as barcode scanners, optical character recognition, RFID, and the like. In some embodiments, the computing device 112 includes such automation systems, and in other embodiments, the automated systems are coupled to the computing device 112 via suitable wireless or wired communication protocols.

In some embodiments, the measurement data can be associated with the DUT 104 prior to the computing device 112 receiving measurement data from the measurement device 108. For example, an asset record corresponding to the DUT may be selected or created prior to receiving the measurement data from the measurement device 108, thereby associating the subsequently received measurement data with the DUT 104. In other embodiments, the measurement data is to be associated with the asset 104 after receiving the measurement data from the measurement device 108. For instance, upon receiving measurement data, the associated asset record may be created, selected, etc., thereby associating the received measurement data with the DUT 104.

The interface 256 may further provide a graphical list of assets to be tested (DUTs 104). In particular, the interface 256 may provide the identity and/or location of each of the assets on the list. For instance, the interface 256 may include a graphical map illustrating each asset to be tested in a particular environment. In some embodiments, the interface 256 may further indicate the order in which each asset is to be tested. FIG. 20 is a representative interface illustrating one example of a maintenance route, as will be described in more detail below.

As briefly described above, one or more embodiments of the interface 256 are capable of generating one or more interfaces for presentation to a user, such as a technician or the like. In some embodiments, execution of the interface 256 presents a navigation interface 510 on the display 270 (see FIG. 2). One example of the navigation interface is shown in FIG. 5. The navigation interface 510 may combine multiple types of information to provide an integrated view of data stored and data to be collected within the system 100 in an organized and efficient manner. The navigation interface 510 may provide functionality that guides the user through activities related to maintenance or calibration information obtained and maintained by the system 100.

In the embodiment of FIG. 5, the navigation interface 510 includes a plurality of interface elements, such as icons, hyperlinks, etc. The interface elements in one embodiment may include one or more of the following in any combination: Take images interface element 514; Browse interface element 516; Assets interface element 518; Routes interface element 520; Help interface element 522, Library interface element 521; Connect devices interface element 524; Compare images interface element 526; View data interface element 528; among others. Upon execution of one of the interface elements, another associated interface is presented via the display for interaction with the user.

FIGS. 6-20 depict examples of other associated interfaces that may be presented via the display for interaction with the user. FIG. 6 is one example of a Connect devices interface 610 that is generated by the interface 256 and presented to the user via the display 270 upon actuation of, for example, the Connect devices interface element 524 in FIG. 5.

Once coupled, the computing device 112 is associated with the measurement device 108.

In other embodiments, the Connect devices interface 610 may also include a list 630 of one or more measurement devices that can be selected by the user for the coupling process. The list 630 can be in depicted as words, icons, combinations thereof, etc. In some embodiments, the list 630 may be historically generated, a list pre-stored in memory 250, the previous, for example, four (4) coupled measurement devices, or the list may be a list of all of the measurement devices that are in proximity of the computing device 112 and are capable of being coupled thereto. The Connect devices interface 610 may further depict the one or more signals indicative of measurement data received from a measurement device in a graphical manner as indicated at 640. The Connect devices interface 610 may also include navigational interface elements that include, for example, a Home interface element 652, a Back interface element 654, a Next interface element 656, a Done interface element 658, etc.

FIG. 7A is one example of a Library interface 710 that is generated by the interface 256 and presented to the user via the display 270 upon actuation of, for example, the Library interface element 521 in FIG. 5. As best shown in FIG. 7A, among other things, the Library interface 710 may include one or more images 712A-712N of a DUT, such as an electric motor, and/or information 718 in the form of text, etc., of the asset in question, and/or the like. In the example shown in FIG. 7, the information may include common maintenance problems with the DUT, general service or testing information, normal operational parameters of the DUT, etc. The Library interface 710 also includes navigational interface elements that include, for example, Home interface element 722, Back interface element 724, Next interface element 726, Done interface element 728, etc.

FIG. 7B is another example of a Library interface 760 that is generated by the interface 256 and presented to the user via the display 270. The Library interface 760 may be generated upon actuation of, for example, the Library interface element 521 in FIG. 5, actuation of other interface elements, such as the Next interface element 726 (see FIG. 7A), among others. In any case, the Library interface 760 may include one or more images 764A-764N of an asset, such as an electric motor, and/or information 770 in the form of text, etc., of the asset in question, and/or the like. In the example shown in FIG. 7B, the information 770 may be in the form of maintenance issues common to the DUT, although other information may be alternatively or additional presented.

FIG. 8 is one example of an Assets interface 810 that is generated by the interface 256 and presented to the user via the display 270 upon actuation of, for example, the Assets interface element 518 in FIG. 5.

At block 320, a computing device, such as computing device 112 (FIG. 1), is placed in proximity with a measurement device, such as measurement device 108 (FIG. 1) and coupled in communication with the measurement device 108. In some embodiments, a communication link can be established automatically while in other embodiments, the communication link is established via user input, such as through the Connect devices interface 610. At block 330, prior to or while the computing device is coupled to the measurement device, one or more parameters of a device under test are measured by the measurement device 108 to obtain measurement data. At block 340, the measurement data is transmitted from the measurement device 108 to the computing device 112. At block 360, the measurement data is associated with the device under test to obtain associated measurement data. In some embodiments, the measurement data is associated with the device under test (DUT) by selecting the DUT from a list of devices on the computer device 112. Alternatively, identity information (e.g., name, serial number, etc.) about the DUT can be obtained by the computing device 112 via an automating system 276 and associated with the measurement data. In other embodiments, the measurement data is associated with the device under test (DUT) by accessing an asset record corresponding to the DUT. At block 370, the associated measurement data is provided to a maintenance service provider 124 via a network, such as network 116 (FIG. 1). The method ends at block 380.

The above blocks may be performed sequentially, in parallel, or in a different order than those described herein. It is to be appreciated that in some implementations one or more of the illustrated blocks may be eliminated, combined, or separated into additional blocks. Furthermore, the method 300 may include additional blocks not shown.

The system 400 is substantially identical in components and operation as the system 100 of FIG. 1, except for the differences that will be described in greater detail below. For clarity in the ensuing descriptions, numeral references of like elements of the system 100 are similar, but in the 400 series for the illustrated embodiment and an explanation of the function and operation of these components will not be repeated. As is best shown in FIG. 4, the system 400 includes a measurement device 408 comprising a computing device 412 that is substantially similar in components and operation to the computing device 112 of FIG. 1. The measurement device 408 further includes at least one measuring device 414, such as a sensor, probe, and the like, to measure one or more parameters of the asset 404.
